-/* The GCC global register variable extension is used to reserve some
- host registers for use by generated code. However only the core parts of
- the translation engine are compiled with these settings. We must manually
- save/restore these registers when called from regular code.
- It is not sufficient to save/restore T0 et. al. as these may be declared
- with a datatype smaller than the actual register. */
